Accelerated & Real-Time Aging

The Accelerate Aging test simulates real-time aging using elevated temperatures to artificially speed up the aging process. This test enables manufacturers to get their product to market faster. Accelerated aging is optional, but real-time aging is required when establishing an expiration date.

Real-time aging is done at normal storage conditions. Additional testing is performed after aging to access the packaging and/or product performance.

Study Outline

The Accelerated Aging test can be run to simulate a designated time period ranging from 1 month to 5 years (or longer). The time of simulated aging depends on the temperature at which the products are held. For example, at 55°C using an ambient temperature of 25°C, 6.5 weeks is equivalent to 1 year on the shelf. So at these parameters, 13.0 weeks would be equivalent to 2 years on the shelf and 32.5 weeks would be equivalent to 5 years on the shelf.

After the samples have been aged, they are removed from the chamber and brought back to room temperature. Following the aging, the samples can be returned to you for further examination (such as functionality tests), or we will retain the samples to perform additional testing to confirm stability (i.e., package integrity/microbial aerosol barrier challenge, seal peel, or other physical tests).

Recommended replicates: You may age as many samples as you need. The number of samples should be based on the number of time periods to be examined, and the testing to be performed after aging.
